I ended up with the Raybrig after a whole weekend of racing. I was going thru the stack of junky prize cars in my garage, just deleting, but something made me stop at the Raybrig, and take it to midfield for a test drive. Man I'm glad I kept it, after a little tweaking it was amazing, and I thought "My god I almost deleted this, and it's the best regular type car in the game".
This is an NSX that you can strap a turbo on, and that's really pretty amazing when you think about it. My Raybrig is up to 1033 HP now, and it rides pretty steady for me down straights. Maniac, it sounds to me like maybe the toe-in settings on your wheels might need a bit of adjusting. Also your times are amazing you're like 5 seconds faster than me at least lol.
Write down the settings you have now on your car, and then try these
springs - 14.5 / 16.8
Ride - 45mm / 45mm
Bound - 7/7
Rebound - 7/7
Camber - 2.0 / 1.0
Toe - 0.0 / -1.0
Stabs - 5/5
Brakes - 15/10
LSD - 10/60/60
Trans: Auto 32
1- 3.966
2- 2.656
3- 1.933
4- 1.475
5- 1.167
6- 0.868
Final - 4.062
Down - 0.66 / 0.66
ASM - 20
TCS - 10
And thats how I ride it, it's really stable to me. I have always been happy with the Raybrig because it will do just about anything I ask it to
